/* ==========================================================================
   Tempered Studio — THE stylesheet
   One shared design system for the homepage and every individual app page.
   Used by: index.html, apps/dandle.html, apps/today-hub.html,
            apps/app-template.html, and anything else you add to apps/.

   App pages override only three variables (--accent, --accent-deep,
   --accent-warm) in their own tiny inline <style> block. Everything else —
   type, spacing, nav, footer, buttons, every component below — comes
   from here, so no page ever has to reinvent its own chrome.
